author-workflow-skills

author-workflow-skills is a skill for Claude Code, Codex from radiantlogicinc/fastworkflow. It costs 161 tokens per session (6,216 once invoked), scanned A, original, Apache-2.0.

A Python file format for defining reusable, parameterized jobs for a coding agent. It turns each job's phases and steps into the agent's numbered plan.

In plain words
What is it for?
Use it to design agent skills with typed inputs, several phases, generated plan steps, and code-run actions.
Why use it?
It avoids rebuilding multi-step workflows as one-off commands and lets related phases pass facts to one another.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

author-workflow-skills scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 17d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 310 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Writing workflow skills

A skill is one Python file, _skills/<name>.py, next to _commands/, written like a command file. Its Signature describes a job and its Input declares the job's typed arguments, exactly as a command's; where a command has a ResponseGenerator (it generates a response), a skill has a PlanGenerator (it generates a plan): each public method is a phase that returns its steps as text. At run time the skill matcher picks the skill for a request (workflow_agent.match_skill, from the description and plain_utterances), the planner fills Input in one typed call (skill_commands.plan_skill_call), the arguments are checked, and the steps become the agent's numbered plan.

The one-page guide is docs/skill_file_layout.md in the fastworkflow repository (not in the wheel), with the preview; docs/skill_phases.md covers phases, facts, code-run steps and answers. The module documentation of fastworkflow.skill (the form), fastworkflow.skill_commands and fastworkflow.skill_phases (the runtime) ships with the package and is the source of truth.

Code references below name a module of the fastworkflow package and a symbol in it.

Skill or command?

Write a command (_commands/<name>.py) when Write a skill (_skills/<name>.py) when
it is one action on the application (wraps code, returns an Output) a family of requests is answered by the same several commands in a known order (find, open, read, answer)
the agent should choose it by intent the agent keeps getting the order, a value or the answer wrong for that family
it needs to read state or call a backend the job only needs text: PlanGenerator methods build text and must not call a backend or read state (skill_commands module doc)

A skill adds no capability: every step it writes runs an existing command (checked at load). A one-command skill is a command with a worse name. Fixed steps with no parameters are allowed (a PlanGenerator with one method taking no input): the text planner adapts them. A skill with no parameters may also have phases: every call has the one plan, and the planner's skill call has no arguments (skill_commands.py skill_from_parts).

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
